Fort Worth Roofing: Article About Synthetic Underlayment
Before the shingles are installed on a roof, most professional Fort Worth roofing contractors install an underlayment over the decking. This underlayment serves several purposes. First, it prevents water from causing damage to the deck should it rain before the shingles can be installed. Second, it keeps moisture from getting into a home through the roof joints. Finally, it prevents tar and other contaminants that may leach from the shingles from damaging the deck. Currently, there are several choices when it comes to which type of underlayment may be used. However, many roofers are choosing to use synthetic underlayment due to the number of advantages it provides.
Synthetic underlayment can be made from a number of different manufactured products, including fiberglass, polyester and polypropylene. In fact, this material is often used for products not related to construction, such as food storage containers and even rope.
There are some advantages to using this type of underlayment over felt. Synthetic underlayment is much lighter than traditional roofing felt, making it much easier to work with. Although they are both resistant to water and vapor, they are also able to withstand high winds in the event that the shingles are torn off. Unlike roofing felt, the synthetic underlayment will lay flat after getting wet, which allows the shingles to be installed easily and correctly.

Finally, this type of underlayment is much safer for professional roofers to walk on.
However, there are also a few concerns associated with using synthetic underlayment. One of the main problems is that there are no set standards for the different products. Because of this, using certain types of synthetic underlayment could void some manufacturers' warranties for asphalt shingles. Additionally, wicking can be a huge problem, especially if the material is not properly installed around the roof eaves. If the underlayment is not installed properly, the building owner could have some major problems with moisture in the future.
Each type of synthetic underlayment is a bit different. Some are fastened to the roof using either roofing nails or plastic caps, but the use of roofing nails is generally discouraged. Additionally, some synthetic underlayment types have slope limitations that are specified by the manufacturer.
There may be some cases when synthetic underlayment may not be the best choice for a home. For example, if the roof has a steep slope, a roofer may recommend going with roofing felt. Regardless of which type of underlayment is used, it should properly protect the roof should something happen to the shingles.
